That would make it a different zone for each player. That's why if a robotic system is implemented, IMO, you would have to change the strike zone to a fixed zone. That way, no matter what the stance or height of a person is, the zone would be the same for everyone. The bottom and top of the strike zone would be so many inches, and the plate of course would be the other measurement. Of course this is a huge change from the historical strike zone. And adjustments will need to be made. My guess is, with a 3d robotic system, the strike zone will become smaller, probably the area around the waist. Because top to bottom, the movement is greater than left to right. And guys like Kershaw will be feasting on dropping the ball down into the back of the zone from above the head.
